Abstract

The high number of defective products can cause the company to receive many complaints. This research aimed to apply the quality improvement approach i.e., the DMAIC methodology (Define-Measure-Analysis-Improve-Control), to reduce product defect. The object of discussion was the black-color cloth hangers produced by the injection machine. The absence of definite standards regarding the parameter settings for the injection machine was suspected to be a reason for the high number of defective products. Therefore, adopting the Response Surface Methodology (RSM) into the DMAIC phases can bring the optimization result. when the experimental design called-as Box-Behnken was applied. The measurement of the initial condition before improvement showed that the sigma level of the injection process was 3.64 (out of 6), with the dominant types of product defects being flash, short mold, and lack of the color black. By implementing the RSM, the experiment produced the optimum setting of the injection machine: 180°C for barrel temperature, 35 bars for injection pressure, and 41% for injection speed index. After implementing the proposed improvements, the sigma level was increased to 3.90.
